INTRODUCTION

The PRX715XLF extended low frequency subwoofer was designed and engineered

to provide sub bass frequencies with accuracy and power. Used as a single sub

in a sub/sat system or in multiples as part of a scalable, large format sound

reinforcement system, the jbl prx715xlf performs with exceptional efficiency and control.

Features:

? Maximum SPL Output 131 dB Peak

? 15" Differential Drive low-frequency driver for low-distortion and higher SPL

? 1500W highly efficient Class-D amplifier

? DSP input limiter circuit, crossover, dynamic limiting, and component optimization

? Professional XLR-1/4" combination inputs and XLR loop-through

? Top panel M20 pole mount socket for sub/satellite configuration

? Injection molded handles with comfort rubber grips for easy transport

? Lightweight poplar plywood cabinets made structurally sound with tongue and

groove joints and protected by JBL’s tour proven Dura Flex finish.

Application:

The subs are stackable and lightweight ensuring quick set-ups and teardowns. And due to

their rugged construction are perfect for AV rental inventories. With a pole receptacle

(that accepts a SS4-BK or SS4-BK24) on the top panel and integrated stereo pass-thru this

is the most powerful low-frequency complement to the PRX full- The range systems.

addition of a polarity reverse option further enables system optimization.

The PRX715XLF is a high performance self-powered subwoofer system. The

PRX715XLF is comprised of a powerful 2275H Differential Drive dual voice-coil

and magnetic gap, woofer driven by a 1500 Watt Class-D power amplifier.

Sophisticated DSP is at the core of a fully featured input section, providing user

selectable cross-over functionality, polarity optimization, protection, dynamic limiting

and discrete component optimization.

All PRX700 cabinets are built from a combination of 25 mm (on the top and

bottom for added rigidity) and 18 mm, strong, light-weight poplar plywood made

structurally sound with tongue and groove joints. All PRX700 Series cabinets

are protected by JBL’s tour proven Dura Flex finish. Grilles are made from

dent-resistant 16 gauge steel and handles are made from light-weight glass-filled

nylon for added strength and durability.

The amplifier input panel offers stereo inputs with XLR or ¼ inch jack

compatibility. A user selectable crossover ensures a smooth transition to full-range

system connected to the stereo outputs. Signal present and limiter lights indicate

the system status and assist in setting the optimum level via the level control knob.
